This study aimed to analyze human immunodeficiency virus (HIV) mutation profiles related to antiretroviral resistance following therapeutic failure, and the distribution of hiv subtypes in the Northeast Region of Brazil. A total of 576 blood samples from AIDS patients presenting therapeutic failure between 2002 and 2004 were analyzed. The genotyping kit(More)
To assess the prevalence of primary resistance of human immunodeficiency virus type 1 (HIV-1) to antiretrovirals, 84 patients chronically infected with HIV without prior antiretroviral treatment from Northeast Brazil were studied. Genotyping was performed using the ViroSeq Genotyping System. Thimidine analog mutations occurred in 3 (3.6%) patients.(More)
UNLABELLED The BED capture enzyme immunoassay test makes it possible to determine whether individuals were recently infected with HIV. OBJECTIVE In this study, the overall HIV and recent infections prevalences were determined at five Voluntary Counseling and Testing (VCT) centers, in the Metropolitan Region of Recife, Northeastern of Brazil. MATERIAL(More)
Determining the prevalence and type of antiretroviral (ARV) resistance among ARV-naïve individuals is important to assess the potential responses of these individuals to first-line regimens. The prevalence of primary resistance and the occurrence of recent infections among individuals with human immunodeficiency virus (HIV)/acquired immune deficiency(More)
BACKGROUND Hypertension (HBP) is modifiable risk factor, whose control may reduce cardiovascular disease in patients with human immunodeficiency virus (HIV). OBJECTIVE To estimate the prevalence of hypertension and describe the characteristics of patients with hypertension infected by HIV/AIDS. METHODS A cross-sectional study aligned to a cohort of(More)
Forty-five individuals with hepatosplenic schistosomiasis mansoni were studied with the aim of measuring levels of von Willebrand factor antigen (vWF:Ag), detecting abnormalities in platelet morphology and aggregation, and identifying changes to surface antigens. Haemograms, platelet aggregation tests, flow cytometry investigations of CD41/CD42b antibody(More)
This paper shows data regarding dengue and hemorrhagic fever of the dengue epidemic in Recife in 2002 and the clinical, laboratorial and necropsy results from the 14 patients who died that year. The serotype Den-3 was detected in 76.3% of cases. The majority of deaths occurred among men, over 20 years old, on the 11th day of disease, attended in the private(More)
The authors compared demographic aspects and profile of mutations in 80 patients with subtypes B and F of human immunodeficiency type 1 (HIV-1). Genotyping of the pol region of the reverse transcriptase was performed using the ViroSeq Genotyping System. A total of 61 (76.2%) patients had subtype B and 19 (23.8%) subtype F of the HIV-1. Subtype F tended to(More)
The effects of HIV/AIDS and antiretroviral drugs on vitamin D metabolism are still mostly unknown. This was a cross-sectional study to estimate the prevalence of vitamin D deficiency and identify its association with the clinical and metabolic parameters among 214 HIV-positive female patients on antiretroviral therapy (ART) in Brazil. The prevalence of(More)
BACKGROUND The measurement of CD4+ T-cell (CD4) counts is a strong predictor of progression to AIDS and a means of monitoring antiviral therapy (ART). The success or failure of controlling virus levels in untreated patients or those taking ART may be associated with treatment adherence, habits, correlated infections unrelated to HIV, cancer,(More)
